There's basically no scenario where it's sensible for this to match dropped columns, so put a test for dropped-ness into SPI_fnumber() itself, and excise the test from the small number of callers that were paying attention to the case. (Most weren't :-(.) In passing, normalize tests at call sites: always reject attnum <= 0 if we're disallowing system columns. Previously there was a mixture of "< 0" and "<= 0" tests. This makes no practical difference since SPI_fnumber() never returns 0, but I'm feeling pedantic today. Also, in the places that are actually live user-facing code and not legacy cruft, distinguish "column not found" from "can't handle system column". Per discussion with Jim Nasby; thi supersedes his original patch that just changed the behavior at one call site. Discussion: <b2de8258-c4c0-1cb8-7b97-e8538e5c975c@BlueTreble.com> |
